Soar over the Chiltern skies with Kitty Milvus, a young red kite. Kitty and her best friend Azalea have started training for the Annual Airshow, a competition which tests a kite's agility, speed, nerve and airborne skill. Both girls have been dreaming of victory their entire lives. However, on the day of the finals, Kitty's plans are dashed, and she has to make a choice: save her sister or her victory. However, the choice is not as easy as it seems. There is a very high chance her sister is dead, and red kites do not have the same connection with their siblings as humans do.
